ST Series - Feed Trailer

Find a Dealer

The ST Series twin screw rear unload feed trailer has twin floor augers that allow for a lower body height and also increased stability since more of the load is closer to the frame. Steep 45 degree sloped sides make for reliable unloading and the large lower body means more capacity. Excellent clean out and little cross-contamination are two benefits of having twin floor augers.

Unload speed: 3,500 pounds per minute     Capacities: 960-1,750 cubic feet
